CONNECTION FOR BUILDING COLUMNS.

Application filed September 1, 1925.

To all wiz/0m t may concern Be it known that I, .lor-IN LALLY, a citizen of thc United States, residing at Great Nec-k, in the count-y of Nassau and State of' New York, have invent-ed certain new and useful Improvements in Connections for Building Columns, of which the following is aspecification.

My invention relates to improvements in connections between superimposed building columns and it is my object to produce a connection of stock material which might otherwise be waste whereby columns of the same or different diameters may be solidly united, and the parts of' which connections will be integral parts of factory-made columns, produced at a low cost and with a minimum of material and which may be quickly erected on the job by merely bolting the parts together.

In the drawings Fig. 1 is a side view, partly in section, of my improved connection; and Fig. 2 a view, partly in section, of the structure of Fig. 1 on the line 2-2 thereof.

The upper column 1 is of' the usual type and is composed of a steel shell 2 with a filling of plastic material 3. The shell is slotted near its lower end at 4; and a connection formed with a web 5 and a flange 6 is placed in the slot et with thc part 7 of the web, left after cutting away a part of the web and flange, within the shell and with the flange 6 substantially on a line with the bottom of the column. This connection is, in practice, made of a piece of rolled T-beam of suitable dimensions.

A wedge or key 8 may be driven through a slot in the part 7 of the connection web inside of the shell 2 to lock the connection in place. The connection may also be welded to the slot if desired.

The lower column 9 is also formed of a steel shell 10 with a plastic filling 11 and is slotted at 12, near its upper end. A connection 13, like the connection 5, is placed in the slot and secured therein, with its flange 14 substantially in line with the top of the column 9.

One or more of these flanged connections may be inserted in each column as occasion requires.

In erecting the columns I prefer to insert a sandwich plate 15 between the upper Serial No. 53,874.

and lower columns to prevent the plastic fillings coming into contact. This is especially necessary where the columns are of differentdiameters or where a floor beam is to be connected to the columns. When the columns are erected bolts 16, or other suitable means, are passed through the flanges 6 and 14 of the connections, which are factory drilled, and the upper and lower columns are thereby solidly united.

In Fig. 1 I have shown how a floor beam 17 may be secured to a connection 18 on the upper end of the lower column and have its flange secured to the connection on the lower end of the upper column, thus tying all the parts together.

I claim 1. In a building column, a tubular metal shell slotted near one end and a connection comprising a web and a flange, the web of' which extends through the shell slot into the interior thereof with the flange substantially alined with the end of the column and means for securing the connection to the shell.

2. In a building column, a tubular metal shell slotted near one end and a. connection comprising a web and a flange, a portion of the web and flange being cut away with the remaining portion of the web above the cutinserted in the slot and extending into the shell and the flange substantially alined with the end ofthe column and means for securing the connection to the shell.

3. In a building column, a tubular metal shell slotted near one end and a connection comprising a web and a` flange, a portion of the web and flange being cut away with the remaining portion of the web above the cut inserted in the slot and extending into the shell and the flange substantially alined with the end of the column and a key passing through a slot in the web within the shell to lock the connection and shell together.

t. Building column construction comprising superimposed upper and lower columns each consisting of a meta-l shell slotted near its end, a connection in each of said slots comprising a web and a flange, the web portion extending through the slot into the shell and the flange in substantial alinement with the column end, means for securing the connections to the shells and means for uniting the flanges of the connections whereby the Columns will be united.

5. Building Column construct-ion comprising superimposed upper and lowel` columns each consisting of a metal shell slotted near its end, a connection in each of said slots comprising a web and a flange, the web p0rtion extending through Jche slot into the shell and the flange in substantial alinement with the column end, a sandwich plate between 10 the column ends and connections and means for uniting the connection Hanges of the upper and lower column and the sandwich plate.

Y In testimony whereof I have affixed my 15 signature.

JOHN LALLY.
